Moody’s threatens WaMu covered bond downgrade

Moody’s has put on review for downgrade the triple-A ratings of WM Covered Bond Programme issues, after cutting Washington Mutual Inc from A3 to Baa2 and Washington Mutual Bank from A2 to Baa1, both with stable outlook. The rating agency had said in its pre-sale report that the covered bonds could come under pressure if WaMu Bank’s rating fell below A3.
